Problems solved by technology

Obviously, in the existing technology, relying solely on printers is far from being able to meet the real-time supporting needs of the production line, so we can only print the printed matter first, and then manually distribute the printed matter to the product for the second time, which is extremely troublesome

Embodiment 1

[0048] figure 2 , image 3 , Figure 8 , Figure 4 As shown, the sheet-fed changing graphics and text printing equipment includes an inkjet head 5 and a microprocessor. The microprocessor stores the data information of printing graphics and texts. Ink action, the inkjet head 5 is equipped with an ink cartridge 51, and a paper pad member is provided under the inkjet head 5. The paper pad member under the inkjet head is a circular roller 1 with a diameter equal to 80CM, and the circular roller 1 A rotating shaft 10 is provided, and the extension direction of the rotating shaft 10 is the front-to-back direction, the inkjet head 5 is close to the circumferential surface of the circular roller 1, and the ejection direction of the inkjet head 5 is the radial direction of the circular roller 1; A plurality of inkjet heads 5 are arranged in a circumferential arrangement, and the distance between each inkjet head 5 and the central axis of the circular roller is equal. The surface ...

Embodiment 2

[0054] A method for printing changing graphics and text on a sheet of paper, using the equipment for printing changing graphics and text on a sheet of paper according to Embodiment 1, comprising the following steps:

[0055] (1), input the data information of the paper 8 to be printed into the microprocessor; the external air pumping part continuously pumps air from the main air pumping hole 41, so that the arc negative pressure chamber 4 maintains negative pressure, and then makes the arc shape Each elongated chamber 16 of the circular roller aligned with the middle section of the arc-shaped opening 43 of the negative pressure chamber 4 continuously forms a stable negative pressure;

[0056](2) The circular paper transfer part (circular paper transfer sprocket 2) of the paper transfer mechanism is constantly rotating, and the paper transfer chain 22 is driven by the circular paper transfer sprocket 2. The paper bite 21 bites the front edge of the paper 8 and drives the paper ...

Abstract

A single-sheet paper-changing graphic printing device, including an inkjet head and a microprocessor, the microprocessor is connected to the inkjet head and controls the inkjet action of the inkjet head, and the paper pad member under the inkjet head is a circle There are many small air holes on the peripheral wall of the circular roller; there is also an arc-shaped negative pressure chamber next to the circular roller, and the arc-shaped negative pressure chamber is equipped with a total exhaust hole. The chamber is fixedly installed on the frame; each elongated chamber is formed with a side opening facing the arc-shaped negative pressure chamber, and the arc-shaped negative pressure chamber faces the elongated chamber of the circular roller One side of the arc-shaped negative pressure chamber is provided with an arc-shaped opening, and the arc-shaped openings of the arc-shaped negative pressure chamber are at least facing the side openings of the three elongated chambers at the same time. The invention can not only realize the difference of printed pictures and texts of each sheet of paper, but also greatly increase the printing speed of ink-jet pictures and texts. The invention also provides a method for printing changing pictures and texts on a sheet of paper.

Description

technical field [0001] The invention belongs to the technical field of changing graphic and text printing, and in particular relates to a device and method for printing changing graphic and text on a single sheet of paper. Background technique [0002] In the technical field of printing graphics and text, it can be divided into two types according to whether the content of each printing is consistent: the first type is called repeated graphic printing, and the content of each printing is fixed and repeated. , usually this type of printing is equipped with a printing plate, and the printed graphics and texts are engraved on the printing plate in advance, such as traditional gravure printing, offset printing, hot stamping, embossing, etc.; the second type is called changing graphic printing, The printed graphic content of each paper can be set independently according to the needs, and the graphic content printed each time is usually not repeated, such as anti-counterfeiting gr...
